Correct, Mike, my error. But I think we may be getting there. Those primers are not conventional Boxer primers as they have no anvils. Now, I have some brass shotshells with Berdan type priming. If they were reloading those, that would explain the primers for metallic cartridges and also what looks like a decapper for Berdan primers.

(Of course we seem to be sort of assuming all the stuff is for one cartridge/shell, when they might be for separate cartridges and separate guns.)
